This plot

Trending plot for median dark level.

QC parameters is derived from each detector of daily DARK frames.

Name:
Fits header: QC.DARKMED,
QC1 DB: qc_darkmed

Description:
Median of the MASTER_DARK pipeline product frame

Setup:
DET.DIT = 1.0011 sec

DET.NDIT = 1

These plots describe:
Fig. 1. Average view: The QC parameter averaged over all detectors. This view is sensitive to common changes.
Fig. 2. Resolved View: The QC parameter resolved for all detectors.
Fig. 3. Scatter View: The standard deviation of the QC parameter, obtained from the sample of all detectors. This view is sensitive changes of individual detectors.
Fig. 4. Scoring View: Scoring values of all 16 QC parameters. Green = within the acceptance thresholds. Red = beyond the acceptance thresholds.

General information

Click on any of the plots to see a close-up version.

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.

The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
  • you can download the data for each parameter set if the 'Data downloads' link shows up
